Electronic Watchdog

      This disclosure outlines a tracking and control system using
Multimedia computers to augment guards at secure locations.

      Visitors and workers would be issued a passive identification
card (see below) and be authenticated at each major intersection.
Their path to and from authorized work areas would be both monitored
and verbally directed to insure their direct travel.  This technique
can be expanded to a file drawer level if desired.  Prior Art
requires Active use (e.g. Guards inserting key in station or users
inserting Magnetic card in reader) which is ineffective for proper

      Control Elements:

1.  Hardware Elements.  (Refer to the figure)

    a.  Multimedia Computer (10) with control program described
    b.  The Passive Identification Card (20) utilizes existing
        passive detection technology.  The card has imbedded in it a
        resonating circuit that can be queried by stationary sensors.
        The visitor would be required to have the badge on them at
        all times.  Each visitor would be issued a unique frequency.
        For cost and privacy needs, employees need only be issued
        cards for a 'class' of user access.
    c.  The Sensors (30) would monitor a control area every fraction
        of a second to sense BOTH the presence of a card AND motion
        (or infrared, sound..).  This insures that a worker can not
        'forget' their card and travel into inappropriate areas.
    d.  Each sensor station would have an annunciator (40) wired
        directly into the computer control to enable digitally stored
        direction and warning messages.
    e.  The computer would also be connected to an auto-answer phone
        for touch-tone input (50)
    f.  Optional Panic Button (60) can be built into the Passive
        Identification Card (20).  Bending or pressing the card will
        invalidate the resonating circuit indicating a need for
        on-site security personnel.

2.  Software Components

    a.  Authorization Table (100) contains updated list of workers
        and 'classes' of employees authorized in each control area.
        This list also contains the valid TIMES of authorized entry.
    b.  Location Checker (110) periodically queries each sensor (30)
        to determine that only approved personnel are in each control
    c.  Digitized responses (120), A Multimedia (may include Animated
        Video Output) library of directions, warnings, and emergency
    d.  Internal Roadmap (130) contains a 'map' in terms of valid
        paths between sensors (30)
    e.  The Path Director...
